UNITED STATES WILLIAM G. JONES, OIE NIAN'IIC, ILLINOIS.

MOLDING FLASK.

Application filed April 10, 1925. Serial No. 22,042.

To all whom t may concern:

Be it known that I, W'ILLIAM C. JONES, a citizen of the United States, a resident of Niantic, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Molding Flasks, of 'which the following is a specification.

. This invention relates to improvements in molding flasks having particular relation to the hinge and pin construction of the same whereby the separable parts of a molding .fiask may be readily assembled or fit together and disassembled or taken apart.

The object of this invention is the provision of a device of this character which involves the elements of simplicity in oper ation and construction as well as accuracy. Various other objects and advantages will appear from the following specification.

o the accomplishment of the foregoing and such other objects as may hereinafter appear my invention consists in the 0011- struction, combination and arrangement of parts hereinafter described and then sought 'to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof and which show for the purpose of illustrative disclosure one form of my invention and also a modified form of my invention, it being expressly understood, however, that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

Figure 1 is a perspective view of a molding flask provided with a hinge construction embodying my invention, the parts being shown in closed. position.

Figure 2 is a transverse cross section of the construction shown in Figure 1 taken substantially on line 2-2 of Figure 1, the parts, however, being shown in open position.

Figure 3 is a perspective view of the two parts of the hinge construction or pin shown in Figures 1 and 2.

Figure 4 is a perspective view of one end of a molding flask having a modified form of connection also, embodying my invention. 7

Referring now to the drawings the numeral 1 designates one part of a separable molding flask ,and the numeral2 the other part thereof. No novelty is claimed for th fla k it l and, theate s this may "b of any suitable construction.

In the preferred form illustrated the hinge includes two parts which are designated 3 and El; respectively, 3 being the upper part of the hinge and 4 being the lower. This lower part of the hinge has the face or securing plate 5 and projecting therefrom is provided a pair of brackets 6. The top of these brackets is in line with the top of the face or securing plate 5 and they are provided along their top each with a groove or recess 7 which is in alignment with the groove or recess in the other bracket.

The upper member of the hinge is like wise formed with the face or securing plate 8 and is further provided with the outwardly and downwardly extending hinge lug 9, the major portion of which is rounded as shown but having the flat face 10 extending from the junction of the lug 9 with the face or securing this flat portion 10 of the lug is to align and hold the two parts of the hinge and the flask properly and to accomplish that it bears against, the front part of the face or securing plate 5 of the lower hinge mcmher, when the two parts of the flask are in assembled relation. The hinge pin 11 is passed through or otherwise secured to the hinge lug 9 and projects on either side thereof as shown so as to fit within the aligned grooves or recesses 7 of the hinge brackets, it being understood that the hinge lug 9 fits between said hinge brackets. It is also to be noted that when the hinge is thrown to its open position the ends 12 of the hinge brackets 6 will come into engagement with the front face of the face or securing plate 8, causing the same to pivot thereon and to lift the hinge lug 9 and the hinge pin 11 out of engagement with the hinge brackets 6 and the grooves or recesses 7 therein. In that aspect the hinge is automatic in its throw-out function.

I have described one hinge only, it being understood and as shown in the drawings that a plurality of the hinges are utilized on each side of the parts of the molding flask and that in view of their separable construction either side may be opened using the other side as the hinge and the hinge operation as well as the throw-out function will be obtained just the same. This is also true regardless of which part of the hinge is used as the top and which as the lower elem plate 8. The purpose of 17 projecting.

ment, the hinge in this aspect being completely reversible.

In the event it is not necessary or desirable to use a pivot. hinge construction, substantially the same construction may be utilized to give a sliding locking arrangement to the two parts of the flask. This is illustrated in Figure 4 of the drawing. In this figure the two parts of the flask are designated 18 and lland the'lower part of the flask l l has a plurality of hinge members 15 secured. thereto, these hinge members being the same in construction as the lower hinge member l previously described. The upper member 15 of the lockingconstruction is the only one which differs. This includes the face or supporting plate 16 having a lug centrally and downwardly therefrom, this lug corresponding to some extent to the hinge lug 9 previously described. It is provided with the locking pin 18 which is adapted to rest in 'the aligned. grooves or recesses. of thehinge brackets of the lower member, but the. end thereof instead of being rounded to permit a pivotal hinge movement is extended a considerable distance downward as at 19 and provided with the corresponding flat inner face 20 which bears against'the outer face of the face or securing plate of the lower member, fitting between the two brackets of the lower member. This,.therefore, functions as a guide in assembling the two parts of the flask and means for holding them securely together in proper alignment and also as a guide in separating thetwo parts of the flask, in that the movements ofthe parts in separating are guided for a sufiici-ent distance to clear the pattern. The two parts are very securely held in proper position with the manifest advantage that they may be readily and quickly separated without interfering with thecontents of the flask.

What I claim is 1. A molding flask composed oftwo separable parts, securing and aligning means on a plurality of the sides thereof to'holdthe two parts in proper alignment when. assembled, said securing and aligning means, ineluding one member having a pair of outwardly extending brackets provided with aligning grooves or recesses in their upper face and theother of said members having a lugprojecting outwardly and downwardly and adapted to be positioned between said brackets, said lug being provided with a pin to fit. in the grooves or recesses in said brackets, said lug also being formed with a flat face adapted to engage and bear against the front faceof the other aligning and securing member. 7
